YANG Model for ETH TE Topology CCAMP WG, IETF 105, Montreal, Canada draft-zheng-ccamp-client-topo-yang-06 Italo Busi, Haomian Zheng, Aihua Guo (Huawei) Yunbin Xu (CAICT) Yang Zhao (CMCC) Xufeng Liu (Volta Networks) Contributors: Yanlei Zheng, Zhe Liu, Zheyu Fan, Sergio Belotti, Yingxi Yao, Giuseppe Fioccola

Problem Statement (1) Represents ETH access links Inter-layer relationship with server-layer TTP (ILL or TL) VLAN classification & operations capabilities Configure access link bandwidth profiles NE1 NE3 ETH Access Link ETH (Client) Topo Same ILL ETH Client Signal ETH Client Signal TE Tunnel NE2 NE1 NE3 TE Link TE Link Server TE Topo (e.g., OTN)

Problem Statement (2) ETH TE Topology Discovery Support path computation&setup for ETH TE Tunnels/LSPs Yet another technology-specific augmentation of TE Topology model Can support ETH client signals NE1 NE2 NE3 ETH TE Link ETH TE Tunnel ETH Access Link ETH Client Signal ETH (TE & Client) Topo Same ILL NE1 NE2 NE3 ETH TE Topo ETH TE Link ETH TE Tunnel

Approach Augment TE Topology for both ETH TE&Client Topology Network & [RFC8345] Augmentation [draft-ietf-teas-te-topology] TE Topology Augmentation ETH (TE & Client) Topology [draft-zheng-ccamp-client-topo-yang]

YANG Augmentations Attributes Augmentation TE-Bandwidth Augmentations See more details in the draft… For label-start/label-end; For label-step; TE-Label Augmentations For label-hop; For label-restriction;

Summary & Next Step Good Consistency with existing IETF models; Used by Transport NBI DT Applicability Statement I-D; Ask for WG adoption; Model available at: https://github.com/haomianzheng/IETF-ACTN-YANG-Model/tree/master/YANG/ccamp/client-topo-yang Open Issue Alignment with Packet-TE Types and Packet-TE Topology

Thank you!

YANG model for ETH access links

YANG model for ETH link BWP Applicable to ETH access links but also to ETH TE links
